your ta must be mis-informed....however she may just be confused. its not the package that it used to be. there used to be a separate entrance called oscars i think. now that one is gone, and until recently you had to stand in a separate line next to the regular line.
however when we went in october- which by the way took many calls to disey bafter our 90 day window as they didnt open up the packages at the correct time. thanks to my disboard friends who kept me posted whe n it opened! you now have a separate entrance that isnt oscars but it is separate nonetheless.
so you now get your supper altho it can be very early-ours was 330! but we got our stub to be let in at the separte entrace for our F! package. i think your still asked to be there 45-60 mins ahead to get your seats. the very first two sections are for the reserved packages. not nessicarily the greatest seats, but it beats waiting in the regular line for up to two hrs.
if you do a search on F! packages youll bring up sev eral thread most of whihc robo has answered often will full maps on it.
one other tip- if you decide to skip it, the rest of the park is virtually empty while the line is forming and the show going on.
